If you initialize it with a particular number, you will always get the same sequence of numbers.c - How do I generate random numbers without rand() function? If youre after an ultra-simple pseudo-random generator, you can just use a Linear Feedback shift Register. The wikipedia article has some code snippets for you to look at, but basically the code for a 16-bit generator will look something like this (lightly massaged from that page). The randomness comes from atmospheric noise, which for many purposes is better than the pseudo- random How do I generate random numbers in certain range without using rand() function in C? So for every two 85s in the output of this random number generator I think it is important to mention that the random numbers change every time I run the program, which is how I want them to be ( I used srand() with time, and rand() ).android - Random number generator without repetition Class in Java.
